HD3-IN
Pin Name
DAC2 output pin.
In Test mode, it outputs HD or
composite sync signal to
frequency counter.
To improve the driving ability, it
is possible to connect a
resister (minimum: 2 k )
between this pin and GND.
However, when the resister is
added, the output DC voltage
is down.
Input vertical sync signal.
It accepts input of both positive
and negative polarity.
Input horizontal sync signal.
It accepts input of both positive
and negative polarity.
